To all whom it may concern;

Be it known that I, GEORGE D. a citizen'of the United States of residing at Hereford, in the county of Deaf Smith and State of Texas, have invented new and useful Improvements in Actuating vices for Circuit-Closers, of which the following is a specification. 1

This invention relates to actuating devices for the circuit closers of telegraph instruments.

In carrying out the present invention, it is my purpose to provide an actuating device whereby the circuit instruments may be operated to circuit 'closing position in the event of such closers being left open by the operator in charge of the instrument.

Furthermore, I aim to provide a device of this type whereb an open circuit of a telegra h or the li e instrument may be closed rom a remote point in the event that such circuit is openand it is desired to energize the same. i

It is also my pu ose to provide a system of actuating'devices so constructed and arranged that the circuits of any oneor all ofa plurality of telegraph instruments may 'YoUNo,

be closed from a remote point, such as a wire.

chiefs oflice, should any one or all of such circuits be left open inadvertently such as would occur from the vibration of a train in proximity to the instruments" or the care essness of an operator.

The invention also involves an actuating device normally maintained inactive with respect to the circuit closer of the telegra h line by'a normally closed circuit and-diesuch circuit closer to circult closing position upon-the. opening of such normall closed circuit.

With the a ove and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the appended claims.

In theaccompanyin drawing there has been illustrated one pre erred embodiment of my invention and in this drawing; Figure 1 is a diagrammatic view illustratingone application of the present invention. Fig. 2 is'a view in elevation partly in section of an actuating device constructed in accordance with, the present invention. Fig. 3 is a central vertical sectional view taken at right angles to Fig. 2.
